Although atrial fibrillation/atrial flutter (AFib/AFL) are common manifestations of transthyretin amyloid cardiomyopathy (ATTR-CM), a post hoc analysis of the ATTR-ACT study, published April 30 in JACC: CardioOncology, found they do not predict all-cause mortality.

ABSTRACT Background Atrial fibrillation and atrial flutter are relatively rare in young people and the incidence of thromboembolic complications is unknown. Results There were 311 episodes of AFib/AFl among 210 patients with a median age of 17 (IQR 14, 20) years.

The ECG was interpreted as showing atrial flutter with 2:1 conduction. The heart rate could be compatible with that of a 2:1 conducted atrial flutter. Also, lead I could give the initial impression of showing flutter waves. Many advances in treatment have occurred in the 28 years since this article was published.

P utting I t A ll T ogether : — The Rhythm in Figure-1 What we have just described is the following: A regular WCT ( = W ide- C omplex T achycardia ) at a rate very close to 300/minute — without clear sign of atrial activity. Among the fast Supraventricular Rhythms: This is not AFib — because the rhythm is regular.

A deep neural network for 12-lead electrocardiogram interpretation outperforms a conventional algorithm, and its physician over-read, in the diagnosis of atrial fibrillation. M Y A NSWER: In my experience, MAT is the 2nd-most commonly overlooked cardiac arrhythmia ( surpassed only by Atrial Flutter ). GET a 12-lead!

There is atrial activity before every QRS, but that activity has negative polarity, so it is not sinus rhythm. There are clearly no flutter waves, so it is not atrial flutter (a "macro-reentrant" atrial tachycardia) Is it AVNRT originating at the superior pole of the AV node, resulting in a retrograde P-wave before the QRS?
